Hi mike

....Let explain Mike's problem: on 99% of the IS's the tyre wear is due to camber, as the camber drops to the Negative the castor lowers, during the recovery of the camber an "indirect" adjustment of the castor is achieved, when i measured Mike's car the only angle out of spec was the castor

in fact the angle was to low. Now here is the problem i cannot correct the castor becouse the camber is fine, and as i said the castor has "no" direct adjuster. What was being deliberated at the time of the geometry was the "data" overlap, since the data shows three options for the IS200, two of which would "show" better positions for Mike's car, but i chose # three? From memory Mike's index is 00,01 or 02, the data overlap shows
1: IS200 1999-03
2: IS200 (GB) 1999
3: IS200 (GB) 2000-03
the castor data for 1 and 2 is 5deg 46' +- 30'
3= 6deg 7' +- 30'
so for Mike things would read better is i used # 1 or 2 but the facts are his data overlap is #3
Reason
1: IS200 1999-03 is European
2: IS200 (GB) 1999 is that year only
3: IS200 (GB) 2000-03 is Mike's
I cannot explain why his car has a castor setting near to "European" and all other settings @ UK spec, i feel the real explination is down to LEXUS.
